Uhm… “even a car manufacturing giant like BMW could produce 490MWh of solar electricity per year using its own land, or 29 percent of the group-wide electricity demand.”

Uhm. A single 100W bulb running 8 hours per day for a year would consume about a third of a MWh. It seems extremely unlike that BMW’s aggregate consumption is anywhere near as low as described.

http://www.bmwgroup.com/e/0_0_www_bmwgroup_com/verantwortung/svr_2010/_pdf_en/umweltschutz/03_2_Energy_Consumption_and_Emissions_en.pdf suggests that a single plant in near Leipzig could be powered by 4 2.5MW wind turbines. Assuming that average generation is 30% of rated capacity that’d produce a 3MW figure for the plant’s energy draw. 490 MWh of energy would power that single plant for a little less than a month of the year.

One of them may be the GE Durathon.

This is excellent news.

Thanks, Giles.

But what is the “emerging cheap battery storage” that UBS knows about and we don’t? An educated guess or an actual new product that’s about to hit the market?

Awesome! News of the month. Allow me to repost how you calculate years for payback for PV in the case of self-consumption:

yes of we go!!!!

even in holland it is cheaper to use solar than take from the grid!
